Viracucha is a genus of South American wandering spiders first described by Pekka T. Lehtinen in 1967. [2]
As of April 2021 [update] , Viracucha contained seven species: [1]
Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
Amaurobiidae is a family of three-clawed cribellate or ecribellate spiders found in crevices and hollows or under stones where they build retreats, and are often collected in pitfall traps. Unlidded burrows are sometimes quite obvious in crusty, loamy soil. They are difficult to distinguish from related spiders in other families, especially Agelenidae, Desidae and Amphinectidae. Their intra- and interfamilial relationships are contentious. According to the World Spider Catalog, 2019, the family Amaurobiidae includes about 275 species in 49 genera.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
Dwarf sheet spiders (Hahniidae) is a family of araneomorph spiders, first described by Philipp Bertkau in 1878. Their bodies are about 2 millimetres (0.079 in) long, and they build extremely delicate webs in the form of a sheet. Unlike many spiders the web does not lead to a retreat. The silk used in these webs is so fine that they are difficult to spot unless they are coated with dew. They greatly favor locations near water or near moss, and are often found in leaf litter and detritus or on the leaves of shrubs and trees.
Misumenoides is a genus of spiders in the family Thomisidae. Spiders in this family are commonly called "crab" or "flower" spiders.
Balmaceda is a genus of jumping spiders that was first described by George Peckham & Elizabeth Peckham in 1894.
Chira is a genus of jumping spiders that was first described by George Peckham & Elizabeth Peckham in 1896. It is currently named after Rio Chira, a river in Peru, but the Peckhams originally called the genus Shira, later emended by Eugène Simon.
Naubolus is a genus of South American jumping spiders that was first described by Eugène Louis Simon in 1901.
Acanthoctenus is a genus of Central to South American wandering spiders first described by Eugen von Keyserling in 1877.
Dolichognatha is a genus of tropical and subtropical long-jawed orb-weavers that was first described by Octavius Pickard-Cambridge in 1869. Originally placed with the Archaeidae, it was transferred to the Araneidae in 1967, and to the Tetragnathidae in 1981.
This page lists all described species of the spider family Viridasiidae accepted by the World Spider Catalog as of December 2020:
Sidymella is a genus of spider in the family Thomisidae, found in South America, Australia and New Zealand. It was originally named Sidyma, but this was later found to have been used already for a genus of moths.
Auximella is a genus of South American tangled nest spiders first described by Embrik Strand in 1908.
Teudis is a genus of anyphaenid sac spiders first described by O. Pickard-Cambridge in 1896.
Nothroctenus is a genus of South American wandering spiders first described by H. D. Badcock in 1932.
Vitalius is a genus of South American tarantulas that was first described by S. Lucas, P. I. da Silva Jr. & Rogério_Bertani in 1993.
Erissus is a genus of South American crab spiders that was first described by Eugène Louis Simon in 1895.
Strophius is a genus of crab spiders first described by Eugen von Keyserling in 1880.
